The Mavideniz Cutter Suction Dredger designed to dredge rock, clay, silt, sand, and use where the ground is too hard for trailing suction hopper dredgers. Cutter Suction Dredger dredged mechanically by a rotating cutter head, and suitable for land reclamation, deepening harbors and the construction and expansion of ports and navigational channels or for pipeline trenching in the seabed, Construction of sacrificial beach islands and sub-sea berms, Channel and harbour dredging, Land reclamation and coastal protection, Tailings transfer, MFT reclamation & mud farming (Oil Sands), Excavation of glory holes, Trenching for pipelines, Pipe and cable laying and intervention, Placement of protection/pipeline intervention,  Platform and wellhead intervention, Landfalls and shore approaches, Environmental clean up and disposal.

The dredging depth depends on the size of the dredger. Cutter Suction Dredger standard cutter depth is up to 25 m with short ladder and spuds, while a deep suction depth on wires can be reached up to 45 m. You can work all kind of waters including in shallow water areas. All parts of the cutter suction dredger can transport by road, rail or sea. Start with the design; Cutter Suction Dredger has excellent dredge production capacity.

The dredges will handle by the dredge master, all necessary instruments, and steering device are here installed inside the first class operating cabin with air condition, shock absorbers to minimize vibration and noise level and also mounted dredge control and monitoring system, density- and flow rate measuring system, automatic cutter control, suction tube position monitoring, draught and loading monitoring, the velocity of mixture in the delivery pipe and also Reporting – Data logging and Trending.

Cutter Suction Dredger can be self-propelled or require towage between work sites. All hydraulic motors and cylinders operate by one radial piston pump driven by the diesel engine. Improvements in efficiency and savings in fuel consumption are spectacular compared with traditional dredgers. Installed power is significantly less than in other dredgers with similar delivery
pipelines. The diesel engine itself is a modern computer-controlled diesel engine with low fuel consumption, and low NOx and soot emissions.

For additional, Cutter Suction Dredger, cutter depth can be decrease or increase, Anchor boom installation, Spud carriage pontoon, Plain suction installation with jet water pump, Swivel connection for discharge pipeline, Jib crane for changing pump-spare parts, WC, Navigation lights.

After we delivered vessel, you will see the same performance and quality years and years later not changed, there is one reason to catch the performance and quality, We don’t choose cheap products, pick the best material and products for building the Fast Ferry, and also choose the best workers, engineers. We can arrange the designs for your operational profile and requirements.
